(Solved) Compiling Lazarus IDE 2 on Raspberry Pi
lazarus / 1-Linux

----------------------------------------------------------------------

Hi all.

I have been using Lazarus on the Pi for about 4 years now and all
works 100%.
I now got a new Pi 4 with the Buster OS. I did a apt-get install
lazarus and it installed version 2

I need to add some visual componants to the IDE. If I add them from
the online package manager and do a rebuild I get this error.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
lazarus.pp(1,1) Fatal: Cannot find fpdebug used by Lazarus. Check if
package fpdebug creates fpdebug.ppu, check nothing deletes this file
and check that no two packages have access to the unit source..
What could be the issue now ?

Regards.

I have the same error. Also, the Intel based PC with Debian 10 /Buster
does the same thing

Aaaa this is sooo frustrating.

I bought the book "LazarusHandbook" and followed all the steps to the
letter. I got version 2.0.2 installed.

Now if I add packages I get the error

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
lazarus.pp(167,1) Error: Can't call the resource compiler
"/usr/local/bin/fpcres", switching to external mode

Please help me.......

OK so I had to make the swap file 1024 MB. It seems the compiler ran
out of memory.

Now When I want to install packages from the on-line package manager
and now I get errors that the version of FPC is not supported.

Aaaa I want to cry .......

Nobody solved yet?
Will it help to install the older version?

create a swap of 1 GB (1024MB)
- Open /etc/dphys-swapfile as root : Code: Bash
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i sudo nano
/etc/dphys-swapfileGoto the line that says CONF_SWAPSIZE=100
Change that to CONF_SWAPSIZE=1024
Save the file and reboot. ( ctrl-x and yes , sudo reboot)

The reason is that the compiler runs out of available memory.

We have already explained many times that Lazarus needs such a swap
file to successfully build on a Raspberry Pi with 512 or 1024MB
memory...
If you have a Raspberry Pi 4 with 2 or 4 GB these steps are not
necessary anymore.

Note these steps are also necessary for large projects in other
languages like clang or GNU C(++), e.g. building the kernel from
source.
This is not FPC/Lazarus specific.

Hi
I have Raspberry 4 4GB RAM - raspbian-buster
CONF_SWAPSIZE=1024

They don't add packers
lazarus.pp(1,1) Fatal: Cannot find fpdebug used by Lazarus.

packages => install/uninstall packages - fpdebug package not
installed.
add to install - save and rebuilg  IDE

lazarus.pp(1,1) Fatal: Cannot find fpdebug used by Lazarus. Check if
package fpdebug creates fpdebug.ppu, check nothing deletes this file
and check that no two packages have access to the unit source..

How to solve?

I did'nt increase the swapfile, and I had no such problems.
Read the tutorial here:

Good Luck

"lazarus.pp(1,1) Fatal: Cannot find fpdebug used by Lazarus." Would
you write how you solved the problem?
